Materials Characterization REPACK
Characterization, when used in materials science, refers to the broad and general process by which a material's structure and properties are probed and measured. It is a fundamental process in the field of materials science, without which no scientific understanding of engineering materials could be ascertained.[1][2] The scope of the term often differs; some definitions limit the term's use to techniques which study the microscopic structure and properties of materials,[2] while others use the term to refer to any materials analysis process including macroscopic techniques such as mechanical testing, thermal analysis and density calculation.[3] The scale of the structures observed in materials characterization ranges from angstroms, such as in the imaging of individual atoms and chemical bonds, up to centimeters, such as in the imaging of coarse grain structures in metals.

While many characterization techniques have been practiced for centuries, such as basic optical microscopy, new techniques and methodologies are constantly emerging. In particular the advent of the electron microscope and secondary ion mass spectrometry in the 20th century has revolutionized the field, allowing the imaging and analysis of structures and compositions on much smaller scales than was previously possible, leading to a huge increase in the level of understanding as to why different materials show different properties and behaviors.[4] More recently, atomic force microscopy has further increased the maximum possible resolution for analysis of certain samples in the last 30 years.[5]
Microscopy is a category of characterization techniques which probe and map the surface and sub-surface structure of a material. These techniques can use photons, electrons, ions or physical cantilever probes to gather data about a sample's structure on a range of length scales. Some common examples of microscopy techniques include:
Spectroscopy is a category of characterization techniques which use a range of principles to reveal the chemical composition, composition variation, crystal structure and photoelectric properties of materials. Some common examples of spectroscopy techniques include:

Materials Today is a community dedicated to the creation and sharing of materials science knowledge and experience. Supported by Elsevier, we publish high impact peer-reviewed journals, organize academic conferences, broadcast educational webinars and so much more.
The GCI undertakes in-depth scientific studies of broad classes of materials used in cultural heritage to better understand their composition and physical properties and the ways these change over time. Such studies are needed to enable the development of appropriate analytical protocols or the modification of existing procedures, so that a full identification can be made of those materials when analyzed from actual objects or works of art.
In many cases, this research then develops into examining the chemical and physical properties of these art or conservation materials, so that a greater understanding of how they behave and perform can be made. As part of this endeavor, reference materials are also collected, characterized with a range of analytical techniques, and added to the GCI Reference Collection.
Our work in this area tends to focus on classes of materials lacking significant study by the field. Recent areas of research have included plastics, oil paints, waxes, and lacquers. Methodologies developed by the GCI, including analytical methodologies for traditional and modern paints, plastics, and traditional (chemical) photographic processes, are being used around the world for technical studies.

Novel materials are investigated at increasingly smaller scales for maximum control of their physical and chemical properties. Electron microscopy provides researchers with key insight into a wide variety of material characteristics at the micro- to nano-scale.
DualBeam microscopes enable the preparation of high-quality, ultra-thin samples for (S)TEM analysis. Thanks to advanced automation, users with any experience level can obtain expert-level results for a wide range of materials.
Development of materials often requires multi-scale 3D characterization. DualBeam instruments enable serial sectioning of large volumes and subsequent SEM imaging at nanometer scale, which can be processed into high-quality 3D reconstructions of the sample.
Modern materials research is increasingly reliant on nanoscale analysis in three dimensions. 3D characterization, including compositional data for full chemical and structural context, is possible with 3D EM and energy dispersive X-ray spectroscopy. 041b061a72
